CURTAiN-POLE.

SPECIFICATION formingpart of Letters Patent No. 783,287, dated February 21, 1905.

Application filed December 19,1903. Serial No. 185.824.

T0 rtZl whom it may concern:

Be it known that I, JOHN KRODER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Curtain-Pole, of which the following is a full, clear, and exact description.

The invention relates to curtain-poles, curtain-rods, and like fixtures; and its object is to provide a new and improved fastening means for conveniently and removabl y attaching a knob to the end of such fixture and to reinforce the knob to allow of fitting knobs to different-sized poles or rods.

The invention consists of novelfeatures and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a face view of the blank for forming the fastening device for holding the knob on the rod or pole. Fig. 3 is a sectional side elevation of the clamping device, and Fig. 4 is a similar view of a modified form of the same.

The curtain pole or rod A may be solid and of wood, metal, or other material or of tubing, and the hollow knob B, to be attached to the end of the pole or rod A, may be of suitable material and made in any desired manner. The knob B is formed with an opening B, somewhat larger in diameter than the diameter of the pole or rod A, and on the wall of the said opening B is secured a clamping device C for removably holding the knob in position on the end of the pole or rod A. The clamping device C is preferably made from a single disk of spring material and formed with radial slots terminating a distance from the edge of the disk to allow of forming spring bearing-fingers O and attaching-tongues the fingers and tongues both extending integrally from the inner edge of an annular flange or ring C adapted to fit the outer face of the wall of the opening B, as plainly shown in Fig. l; The bases of the fingers C and tongues snugly fit the wall of the opening, and the fingers C extend within the knob and stand at such an angle to the flange O as to bear with their free ends on the peripheral surface of the pole or rod A, as plainly indicated in Fig. l. The attaching-tongues C are bent backward upon the inner face of the wall of the opening B, so as to clamp the wall between the flange or ring C and the said tongues G to securely hold the clamping device C in place on the knob. When the end of the pole is pushed through the opening in the flange or ring C then the spring bearing-fingers O bear on the peripheral face of the rod or pole A with sufficient tension to securely hold the knob in place and at the same time allow of pulling the knob off the end of the pole or rod whenever it is desired to do so. As the fingers G are arranged in a circle, it is evident they bear uniformly on the pole or rod, and as the tongues C are similarly arranged they, in conjunction with the flange or ring 0 securely fasten the clamping device C in position on the knob. In practice I prefer to arrange the bearing-fingers C alternately with the attaching-tongues C and, if desired, the said tongues C 'may be somewhat less in length than the lingers C, as illustrated in Fig. 4.

By the arrangement described it will be seen that the clamping device U strongly reinforces the knob, especially at the pole-opening B, at which the greatest strain is had, thus preventing the knob from being injured while being put on the pole. By having the spring-lingers (1 Standing at angles, as described, they readily engage the ends of poles or rods of different diameters, but within the range of the opening in the flange or ring C". The flange (J is preferably curved, so as to readily conform to the external surface of the knob B, as indicated in the drawings.

By the arrangement described the fastening device for holding the knob in position on the pole or rod A is concealed within the knob B,

as new and desire to secure by Letters Patent-- 1. A ball or knob for attachment to a curtain pole or rod, having an opening for the entrance of the end of the rod or pole, and a clamping device having means for engaging the inner and outer surfaces of the ball or knob adjacent to the opening thereof and provided With fingers projecting into the ball or knob to removably hold the same on the pole or rod, as set forth.

2. A ball or knob for attachment to a curtain pole or rod, having an opening for the entrance of the end of the pole or rod, and a clamping device having an annular flange and provided With tongues engaging the inner Wall of the knob and serving With the flange to secure it to the ball or knob, said device be ing also provided With spring-fingers extending Within the ball or knob and bearing on the said pole or rod, to removably hold the ball or knob thereon, as set forth.

3. A clamping device for fastening a knob to the end of a curtain pole or rod, formed of a single piece of material and consisting of an annular flange, spring-fingers extending at angles therefrom, to bear on the rod or pole,

and attaching-tongues extending from the inner margm of sald annular flange and adapted l to be bent back to form With the flange the means for securingthe clamping device to the knob or ball, as set forth.

4. A ball or knob for attachment to a pole or rod having an opening, and a clamping device formed of a single piece of material and consisting of an annular flange engaging the outer face of the Wall of the said opening, spring fingers extending from the said annular flange and arranged in a circle, to bear on the rod or pole, and attaching-tongues extending from the annular flange and bent back against the inner surface of the Wall of the said opening, to form With the said annular flange the means for securing the clamping device to the knob, as set forth.

5. A clamping device for fastening a knob to a curtain pole or rod, comprising an annular flange, bearing-lingers projecting from the flange for engaging the rod or pole, and attaching-tongues projecting from the flange between the fingers, the Whole being formed from a single piece of spring material, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN KRODER.
